How to choose a Clojure JSON library
clojure, json
Solution
I decided to run a little shootout (the link is to results and the code used to test).
In terms of speed, `clj-json` is the fastest, 1.7x `cheshire`, and 5.6x `clojure.data.json` for a simple parse/generate task.
`clojure.data.json` has the smallest footprint, and `clj-json` and `cheshire` follow. `cheshire` has some superb features, though, and is my preferred library for dealing with JSON. You get support for SMILE, as well as a lovely interface for interpreting JSON (adding types, special rules on keys, etc) and custom encoders (the last also found in `clojure.data.json`).
Problem
There are multiple JSON parser/writer libraries available for Clojure, including: - clojure/data.json - cheshire - clj-json What are the pros and cons of each, especially regarding speed, memory footprint, and programming convenience? Are there any other important factors to consider?
